Battery Backup vs. Standby Generator
Both provide backup power. The right choice depends on your needs. A battery system is silent, requires no fuel, and is ideal for shorter outages and critical loads. A standby generator provides extended runtime as long as fuel is available, which is better for multi-day outages. A.J. LeBlanc Heating installs both EcoFlow and Generac PWRcell batteries as well as Generac and Kohler standby generators, and can help you decide which fits your home and budget.
- Battery: silent, no fuel, instant transfer, limited runtime
- Generator: extended runtime on natural gas or propane, larger capacity
- Both options use an automatic transfer switch and a permitted, licensed install
- Pair a battery with a generator for maximum protection

Frequently Asked Questions
How long can a home battery backup power my house?
It depends on the battery capacity and what you're powering. A typical EcoFlow or Generac PWRcell installation can power critical loads (furnace, refrigerator, lights, outlets) for 8 to 24 hours depending on usage. Multiple batteries can extend that significantly.
Does a home battery require solar panels?
No. EcoFlow whole-home batteries and Generac PWRcell systems can charge from the grid, from solar, or both. Solar is not required to benefit from battery backup.
How does a battery backup compare to a standby generator?
A battery is quieter and requires no fuel, but has limited runtime. A standby generator runs as long as it has fuel. For most NH homeowners concerned about short outages of hours to a day, a battery is a great fit. For multi-day outages, a generator or both is better.
How much does battery backup installation cost in Southern NH?
A Generac PWRcell installation typically runs $15,000 to $25,000 depending on the number of battery modules and any required electrical work. EcoFlow whole-home systems vary based on capacity and the existing panel layout. A.J. LeBlanc Heating provides free written estimates.
